Dinan Free Flow Axle-Back Exhaust for BMW | F10 | 535i | D660-0051

Dinan sport mufflers are designed to compliment the 535i and not overpower the driver and passengers with harsh tones. Dinan engineers their exhausts to sound great and be a natural fit to the character of the car as well as produce more power and torque. Four 3.5" stainless tips engraved with the Dinan logo fill out the rear valence (choose either polished or satin black tips). Annoying highway drone has also been engineered out of the system. Dinan uses only 304 stainless steel in their systems for the maximum corrosion protection. This system replaces the factory rear mufflers at a pre-determined cut point on the stock exhaust, which makes for an easy installation and you can reinstall your original mufflers using factory hardware. Detailed installation instructions are included.

Note: Fits both stock bumper & M-Aerodynamics bumper.

Features:

• +6 HP @ 6600 RPM - +5 lb/ft @ 6600 RPM
• Uses the factory brackets and hangers for a factory-like fitment
• Helmholtz chamber to reduce drone
• 100% 304 stainless steel construction
• Two 3.5" laser engraved polished stainless steel or black ceramic coated exhaust tips
